Effect of atractylone on the viability and apoptosis of hepatoma HepG2 cells and related mechanism
2021
Objective To investigate the effect of atractylone on the viability and apoptosis of hepatoma HepG2 cells and its mechanism of action. Methods Hepatoma HepG2 cells were selected and divided into low-, middle-, and high-dose atractylone groups (5, 10, and 20 μmol/L), and the cells in the control group were added with an equal volume of DMSO. MTT colorimetry was used to measure the viability of HepG2 cells after treatment with different concentrations of atractylone; flow cytometry was used to measure the apoptosis rate and mitochondrial membrane potential of HepG2 cells; the DCFH-DA fluorescent probe labeling method was used to measure the level of reactive oxygen species (ROS) in HepG2 cells; Transwell assay was used to evaluate the effect of atractylone on the migration ability of HepG2 cells; Western blot was used to measure the protein expression levels of Bcl-2, Bax, and cleaved caspase-3. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for comparison between two groups. Results After 24 and 48 hours of treatment with atractylone, compared with the control group, the low-, middle-, and high-dose atractylone groups had a tendency of reduction in cell viability (all P Conclusion Atractylone can induce the apoptosis and inhibit the migration of HepG2 cells, which provides an experimental basis for further development and utilization of atractylone.
